Saturation of multipactor in rectangular waveguide

Summary form only given. Multipactor is a limiting factor in a many RF systems, restricting performance, efficiency, lifetime and reliability. In many situations it is possible to avoid multipactor by various suppression methods or the avoidance of specific operating points. However this cannot always be achieved. When multipactor cannot be avoided, the saturation level becomes critical. In for instance, superconducting applications, multipactor which does not saturate at a low level can limit peak power.
